the system of equatuions 2y = 14 - 2x and y= -x+7 is graphed. what is the solution to the system of equations

Alex73 [517]

Answer:

the solution is the whole line y = -x + 7

Step-by-step explanation:

both equations are identical

2y = 14 - 2x

=> y = 7 - x

which is exactly the same information as y=-x+7

so, there is no single crossing point. they are exactly covering each other. what "remains" is simply the whole line.
